The existing tuning methods of fiber lasers are researched, and they usually cannot take into account the requirements of the tuning range and tuning rate. To solve this problem, a new tuning method based on the photo-thermal effect is proposed, the experimental phenomenon shows that the output wavelength of fiber lasers varies with the pumps power. The static and dynamic tuning characteristics of fiber lasers reveal that the tuning range is about 392 MHz/100 mA and the tuning rate is more than 2 kHz in 980 nm pump source self-tuning. The feasibility of this tuning method has been verified.
